A book is a book, and nothing is comparable to that 'real stuff' as you call it. I never read online, unless it is a very antique book you're not likely to find anywhere else. You can carry your book wherever you go, write on its pages if you like (though it's not useful to me, and I wouldn't do it), and you have it on your shelf in case someday you need to look for a specific quote or paragraph.
I don't think the 'real stuff' is endangered because of Copyright issues, but it may be true that young people (and not so young!) are getting used to reading books online. I don't care haha. I will always choose the book as the best option
